Background:
This preclinical study evaluated the safety and technical feasibility of robot-assisted partial gastrectomy (RPG) using the Carina Platform in a porcine model to accumulate evidence for clinical translation.
Methods:
Six pigs underwent RPG (4 with Plan A, 2 with Plan B setups). The acute group (n = 3) were euthanised 1-h postoperation, while the chronic group (n = 3) survived 28 days for recovery assessment. Operative parameters (time, blood loss), complications, and ergonomics (NASA-TLX) were recorded. Necropsy evaluated surgical site healing.
Results:
All procedures were successfully completed. Mean operative time was 109 ± 34 min. One intraoperative liver injury was controlled without complications. The chronic group showed no infections, with necropsy confirming recovery. Surgeons reported favourable ergonomic scores.
Conclusion:
RPG using the Carina Platform is safe and technically feasible in porcine models, supporting future clinical trials.
